The University of Stuttgart is contributing to innovations for climate protection as part of the EU project "Smart Circular Bridge". An old material is being rediscovered: flax has been with us for thousands of years in the form of clothing, sacks, and robust ship's ropes. Now the plant fibres are experiencing a renaissance and could become the building material of the future.

European collaborative project led by the University of Hohenheim shows: Combining bioethanol production with carbon storage can effectively reduce CO2.

The Ministry for the Environment, Climate Protection and the Energy Sector is funding the new research project RoKKa which is used to prove the viability of recovering raw materials from wastewater. This adds a crucial function to the scope of a conventional sewage treatment plant. Together with the operators of the sewage treatment plants in Erbach and Neu-Ulm, the project partners demonstrate the positive contribution towards climate protection…

The "carbonauten minus CO2 factory 1" will start production of 4,000 t of CO2-reducing plastic granules annually at favorable prices in summer 2022.

pre-start-up company Wheyfinery - 13/04/2022

Acid whey as a valuable raw material for platform chemicals and more

There is not much you can do with acid whey, which is why several million litres of it are disposed of every year. This is both costly and not sustainable. However, researchers at Tübingen University have shown: acid whey can be used to produce precursors for biofuels, fine chemicals and antimicrobial livestock feed additives. They have set up the pre-start-up company Wheyfinery in an endeavour to make their scalable biorefinery concept…

Mini-factories for producing bioplastics - 05/05/2022

Bacteria produce bioplastics: resource-saving and very environmentally friendly

Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.

Renaturalised peatlands as carbon dioxide stores - 14/06/2022

Peatlands as a climate protection factor - binding CO2 instead of releasing it

All intact peatlands on our planet store twice the amount of CO2 as all forests. Peatlands are indispensable for preventing and mitigating the effects of climate change. The only problem is that 95 percent of Germany's peatlands have been drained, and thus release around 7 percent of Germany’s total CO2 emissions into the atmosphere. Rewetting is therefore imperative for the climate, the environment and biodiversity – and economically…

ProteinDistillery GmbH - 20/04/2022

Using microorganisms to create a source of sustainable protein

Yeast has been part of the human diet for thousands of years. ProteinDistillery GmbH now wants to revolutionise the environmentally friendly protein suppliers market by introducing brewer's yeast and secure the protein supply of the future.

The construction industry consumes large amounts of energy resources and produces tons of waste. At the Solar Decathlon Europe 21/22 university competition, students and researchers from KIT are eager to demonstrate that the building sector is already compatible with a functioning circular economy. The task of the interdisciplinary “RoofKIT” team is to convert previously unused roofs of buildings into usable spaces.

Project BW2Pro - 29/08/2022

Biowaste to Products: biorefinery transforms biowaste into new products

In 2020, Germany’s population collected over 5 million tonnes of biowaste. Most of this was composted, and some was fermented into biogas. Scientists in Baden-Württemberg think there's room for more. Within the project ‘Biowaste to Products’ (BW2Pro) they want to transform biowaste into new products in a biorefinery. The idea is to produce biodegradable plant pots, mulch material, fertilisers, enzymes and biobased plastics in addition to…

In Provence, the lavender fields are in full bloom again. This blaze of color may soon also be seen in Baden-Württemberg. In a joint research project, the German Institutes of Textile and Fiber Research Denkendorf (DITF), the University of Hohenheim and the company naturamus are testing suitable lavender varieties and developing energy-efficient methods for producing essential oil from them.

Insect pasta: eating healthily and improving the world at the same time

Insects on the dinner plate? Some people instantly dismiss the idea. Wrongly so, because in terms of animal welfare, ecological footprint and healthy nutrition, insect foods are much better than all other animal foods and are produced in a more controlled way. The fact that they can also taste really good is proven by the start-up Beneto Foods from Albstadt, which has developed protein-rich pasta in various flavours using cricket flour.

More food sustainability: crucial for people and for the environment

Strawberries in winter and imported apples? You can find them in most supermarkets. This is not sustainable. Looking to the future, the way we eat needs to change in many mundane ways – and this needs to happen quickly so that future generations will also be able to enjoy a planet that is worth living on. In Baden-Württemberg, alternative nutrition concepts are being worked at pace. Many creative ideas and innovative products already exist.

Paludiculture as a beacon of hope for the climate - 28/06/2022

Peatlands as CO2 reservoirs: simultaneous renaturation and use

Peatlands store more carbon dioxide than any other ecosystem in the world. However, when drained, they become a climate-damaging source of CO2. The management of wet peatlands reveals exciting solutions, with market potential in the areas of local heating, insulation, packaging and even peat substitution.

Carbon sequestration - 28/07/2022

Carbon farming - climate protection on agricultural land?

Agriculture plays a key role in helping to achieve European climate targets. Central to this goal are measures that are collectively referred to as carbon farming and are often used for offsetting greenhouse gas emissions. Two Baden-Württemberg companies - CarboCert and Carbonfuture - are active in addressing the challenges and potentials of carbon farming.

In its statement of September 2, 2022, the Bioeconomy Council of the German government condemns the Russian war of aggression on Ukraine and points out ways in which the resulting food and energy crisis can be alleviated with the help of the bioeconomy.

More animal welfare and better animal health, more climate protection and less environmental impact: Researchers at the University of Hohenheim in Stuttgart are pursuing these goals with a new approach: They are exploring the interplay between farm animals and the millions of microorganisms in the animals’ digestive tracts. The federal and state governments are supporting the university with the construction of a unique research center for around…

The glass facade of a high-rise building can get so hot that you can fry eggs on it – a major factor in the overheating of our cities. At the same time, flood events such as torrential monsoon rains cause billions of dollars of damage annually. On October 4, 2022, a solution to both problems was presented at the University of Stuttgart.

The Carl Zeiss Foundation is funding the "DELIVER - Data-driven Engineering of Sustainable Living Materials" project at the University of Freiburg in its "CZS Wildcard" program. In the project, scientists from the Freiburg Clusters of Excellence CIBSS and livMatS will develop sustainable wood-based materials whose properties can be precisely controlled.

Basic chemicals, which are needed as raw materials for a wide range of products such as medicines and detergents, can currently only be produced with an enormously high input of energy and raw materials. In many cases, fossil fuels and raw materials are still used. The extraction of chemical substances alone requires high temperatures, expensive catalysts made of precious metals and, in some cases, environmentally harmful starting materials.

Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

Whether in drinking water, food or even in the air: plastic is a global problem - and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed conventional assumptions for the transport of plastic in rivers.

Across the EU, more than 300 billion items of packaging are not recycled every year because they consist of a mixture of different materials. Monomaterial packaging on the other hand is easy to recycle. However, it needs to be coated with ultra-thin barrier layers to protect delicate products just as well as compound materials do.

Festo’s high-tech bioreactor - 10/11/2022

Valuable materials of all kinds - produced automatically in living cells

In future, algae could be used to produce practically everything that still requires petroleum, including plastics, fuels, medicines and food. Algae are also climate savers par excellence, because they bind ten times more CO2 than terrestrial plants. Festo, a company based in Esslingen, Germany, has developed a high-tech bioreactor that can be used to automatically cultivate the small green biofactories - and that do so a hundred times more…
